  • Applications

    Dotriacont-8-enoic acid (CAS 182141-52-2) is a long-chain mono-unsaturated fatty acid used as a chemical building block in several industrial applications. It is commonly employed as an intermediate to prepare wax esters and long-chain lubricants, and as a source for surfactants or emulsifiers in cosmetics and household cleaning products. It can act as a monomer or comonomer in the production of specialty polyesters and other polymers, helping to tailor properties such as hydrophobicity and flexibility. It is also used as an additive in coatings and inks to improve wetting, dispersion and film formation. Additionally, it may serve as a precursor for plasticizers or other specialty chemicals in industrial manufacturing, subject to formulation constraints and local regulations.
